PAPER-BOX uacnnm Application filed September 1, 1920. Serial No.407,461.

- turned or adjusted to bring its flaps into position to be glued orgummed.

A further object is to provide a simple, inexpensive attachment for theurpose described, which Will rapidly shi t or adjust the blanks asreceived from the cutting rolls without interfering with the speed orefficiency of the machine.

A further object is to provide a blank turning attachment of simpleinexpensive construction and one which can be easily applied and will bestrong and durable.

The invention consists generally in the constructions and combinationshereinafter specified and more particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a plan view of a portion of a paper box machine with myinvention applied thereto,

Figure 2 is a longitudinal vertical section of the same, showing themeans for feeding the blanks through the machine.

Figure 3 is a side elevation.

Figure 4 is a detail sectional view showing the relative position of theblank turning means.

In the drawing, 2 represents the frame of the machine. 3 the rollshaving slitting knives 4 in their peripheries for cutting the stock toform box blanks. 5 represents a reel of stock fed over the small rolls 6t0 the slitting knives and 7 and 8 represent conveyer belts supported bysuitable rolls 9, on which belts the blanks are fed through the machine.Between the belts 7 and 8 I arrange shafts 10 and 11 mounted in theframe of the machine respectively above and below a table 13. The shaftsare inclined to the horizontal so that they converge from one side ofthe machine to the other.

Stub shafts 14 and 15 are mounted in the frame of the machine on oneside and have universal joint connections 16 with the shafts l0 and 11,and the stub shafts 14 and 15 have intermeshing gears 17 and 18 thereon,and the shaft 15 is provided with a sprocket wheel 19. A drive belt 20'connects a shaft 21 with the lower slitting roll shaft and also engagesthe sprocket wheels 22 on one of the rolls of the conveyer belts 7 and 8for operating these belts. On the opposite side of the machine a belt 23connects the upper slitting roll shaft with the sprocket wheel 19 fordriving the gears 17 and 18 and the shafts 10 and 11. The table 13 isprovided with openings 24 and 25 therein, and wheels 26 and 27 arearranged in pairs on the shafts 10 and 11, and adjustably securedthereon by suitable means such as setscrews' 28. :The wheels arearranged so that those of the same diameter are opposite each other orin opposing relation through the openings and 25, and both pairs ofWheels revolve in inclined planes, due to the inclination of the shafts10 and 11, on which they are mounted. The peripheries of the wheels arerounded as shown and may have rubber gripping rings or tires thereon,and have sufficient space between them to allow the passage of theblanks.

One pair of wheels, as shown plainly in Figure 4, is of greater diameterthan the other pair and as the shafts revolve at the same speed, thelarger wheels engaging the surface of the blank and having a greatertravel than the smaller wheels, will impart to the blank a rotary orturning movement, causing'it to swing from the position indicated at theright in Figurel to a quarter turn position as indicated at the left inthe same figure,-where the blank'is shown as having passed between thewheels so' that the flap of the blank is at one side instead of in frontas it was before engaging the wheels. A guide plate 29 is adjustablymounted on the frame of the machine by means of slotted arms 30 andbolts 31, and by means of this guide the proper position of the blankmay be determined before its engagement with the narrow belts 32 whichcontinue the feeding movement of the blank through the machine and pastthe gluing or 10 gumming devices. It will be understood that when theblank is engaged by the wheels 26 and 27 that its forward feedingmovement will be continued, but owing to the difference in diameter ofthe wheels, one portion of the blank will travel faster than anotherportion, resulting in partial rota.

- tions to be 1 tion on its support until the flaps, or porgummed orglued are shifted or turned to the side instead of in front of the 15.ing blanks, of means mounted revolving in blank asit left the slittingrolls.

The relative size of the wheels and the speed of revolution may, ofcourse, be va- 1 ried as conditions may require. the main planesinclined to the horizontal to engage the blanks and partially rotatingthem and continuing their forward movement in the same direction.

2. The combination with means for feeding the blanks, of means mountedabove and 5 below the blanks and engaging the surfaces thereof forimparting a combined forward and rotary movement thereto and continuingsaid forward movement in the same direction.

4. The combination, with means for feeding the blanks, of wheels mountedabove and below the blanks and engaging the surfaces thereof forimparting a combined forward and rotary movement and continuing saidforward movement in the same direction.

4. The combination, with means or feeding the blanks, of wheels ofvarying diameter, arranged in pairs above and below the blanks andcontacting therewith, for imparting a combined forward and rotarymovement thereto and continuing said forward movement in the samedirection.

5. The combination, with means for feeding the blanks, of shafts mountedat an incline to the horizontal, above and below the blanks, andmeansmounted on said shafts and engaging the blanks, for imparting a combinedforward and rotary movement thereto and continuing said forward movementin the same direction.

movement thereto and continuing said forward movement in the samedirection.

7. The combination, with means for feeding the blanks, of shafts mountedabove and below the blanks, and inclined to the horizontal, wheelsmounted on said shafts and engaging the surfaces of the blanks, saidwheels being of different diameters, those of the same diameter being inopposing relation for imparting a combined rotary and forward movementto the blanks.

8. In a paper box machine, the combination with the blank slitting rollsand conveyer belts mounted to receive blanks from said rolls, and atable having openings therein and over which the blanks pass, of feedwheels mounted above and below said table and operating through saidopenings to engage and feed the blanks, said Wheels being arranged inpairs'and those of one pair being of greater diameter than those of theother pair whereby a predetermined rotary or turning movement will beimparted to the blanks as they are moved forward.

9. In a paper box machine, the combination, with the blank slittingrolls and conveyer's mounted to receive the'blanks from said rolls, anda support over which said blanks pass, of feed wheels mounted above andbelow said support and operating therethrough to engage and feed theblanks, said wheels being arranged in pairs, those of one pair being ofgreater diameter than thoseof the other pair, whereby a predeterminedrotary or turning movement will be imparted to the blanks as they moveforward.

In witness whereof, I have hereunto set my hand this 27th day of August,1920.
